ALL-YEAR-ROUND ONLINE CONFERENCE SERIES ON EMERGING TECHNOLOGIES
Printed, Hybrid, 3D, InMold, Textile Electronics
When: 24 June 2022 | 14:00 - 19:00 CET
Where: "In-Person Virtual Platform"
Speakers at a glance
About the event
This must-attend event showcases exciting and cutting-edge advances from across the world. It brings together more than 400+ participants, 45 speakers and 55+ live exhibitors. The audience is truly global, coming together across many different time zones.
In this innovation festival, the speakers will present the latest advances and innovations in compact technology-focused 5-min speeches. To continue the discussion, the participants can then visit the speakers in their virtual speaker corner or at their virtual booth.
This is a truly unique gathering in our special 'in-person virtual' platform. This environment is called 'in-person virtual' because it makes virtual interaction real, enabling spontaneous discussions, serendipitous meetings, and excellent networking. We promise- in many ways it is more effective and more fun than onsite in-person interactions.
Spaces are limited and will be assigned on a "first come first served" basis. Please secure your spot immediately.

Micro bumps by gravure offset printing method
We examined to utilize the gravure offset printing method to print high-precision micro bumps with various pastes.
For the flux paste, the precision of the printing position was ±5 μm on a 300 mm wafer.
We have also tried to print and reflow the solder paste.
Printing and reflow have been successful with minimum diameter of 6 μm and 15 μm, respectively.
We will report the details on the day.

Flexible transparent conductive coatings by electrospinning
Transparent conductive coatings are widely used as transparent conductive electrodes in displays, touch screens, solar cells, antenna structures etc., and require a low sheet resistance combined with a high transmission. For wearable electronics and bendable displays, a flexibility of the electrode material is also required. Electrospinning was used as a facile method to produce very long and thin fibers, and in combination with silver, conductivity was introduced.
The properties of silver (Ag) nanoparticle-containing inks and coatings thereof, applied by electrospinning on PET and PC foil substrates were studied. The tested Ag nanoparticle-containing inks consisted of a commercial nanoparticulate silver ink and a polymeric binder in a suitable solvent. The electrospun fibers were fabricated using different spinning conditions and were then silver plated in an electroless process. The resulting coatings have been characterized with respect to their sheet resistance, transmission, and haze.
It was observed that with the electrospun polymer silver fibers, fibers with a diameter of about 1 to 3 µm and lengths of several cm could be obtained, ensuring a high percolation. By variation of the number and the diameter of the fibers, the conductivity and the optical properties could be improved, and coatings with a sheet resistance below 5 Ω/sq were obtained, showing a high transmission of up to 92 % and a low haze below 2 %.
The achieved sheet resistances in combination with the relatively high transmission are comparable to those of other transparent conductive coatings that are state of the art and available on the market, such as ITO coatings. In addition, the coatings produced by this electrospinning process are flexible and stretchable, which offers interesting new applications for wearable electronics and 3D-formable displays, for example. Other advantages of these coatings are the low-cost process for their production and the possibility of upscaling by a roll-to-roll process.
